Variant subraces lose their racial tie if the main race is edited

If a make a race and then a variant of it, the variant shows at the bottom of the main race correctly

If I then edit the main race, the variant no longer displays on the main race's page

In the character builder it still references the old version of the main races

This is only a problem once the race is published, as before then the link address of the main race doesn't change when modified.

The race and variant is question are https://www.dndbeyond.com/characters/races/75950-norn and https://www.dndbeyond.com/characters/subraces/44970-norn-shaman respectively.

Norn Shaman used to display at the bottom of Norn. Then I edited something in Norn. Norn Shaman still points to the old version as its parent race (https://www.dndbeyond.com/characters/races/31811-norn)
